Collagen Regeneration For Skin Elasticity

When the skin in the mirror loses elasticity at some moment and the contour looks like it is collapsing, we often explain that change with the single word “aging.” But in the clinic, at the center of declining skin elasticity there is almost always a decrease in collagen. Collagen is the protein scaffold that supports the dermal layer of the skin, and when this scaffold thins and breaks, the surface sags along with it. In particular, women pass through the hormonal inflection point of menopause, in addition to age, and collagen decreases rapidly. In this article, I will unravel, on a medical-evidence basis, what collagen is, why and how it decreases, and what the principle that can help its recovery is.

Collagen is a structural protein that makes up most of the skin's dermis, supporting the skin so that it does not sag and maintains its form. The skin's collagen is not a single type but several forms with different roles woven together. Among them, type 1 collagen gives the skin tension and firmness, and type 3 collagen is reported to be more involved in elasticity and flexibility. When the two types are woven like a net, the skin has the elasticity to return immediately after being pressed and released.

The cells that make and manage this scaffold are the fibroblasts of the dermis. Fibroblasts synthesize procollagen, the precursor of collagen, and at the same time make water-retaining components such as hyaluronic acid to maintain the skin's plumpness. That is, elasticity is not simply a matter of “moisturizing cream” but a matter of how actively the cells in the dermis are weaving out structural protein.

If you understand how the scaffold of the dermis is composed, it also naturally explains why the symptom of loss of skin elasticity is hard to catch with surface care alone.

Aging means that the balance between the speed of making collagen and the speed of breaking it down collapses. In various studies, the production of type 1 collagen is reported to decrease a little each year after the thirties. At the same time, the number of dermal fibroblasts themselves decreases, and the synthesis ability of the remaining cells also declines, so the amount newly filled cannot keep up with the amount leaving.

To this is added the external factor of ultraviolet light. UV creates reactive oxygen species in the skin, and this signal increases the MMP (matrix metalloproteinase) class of degrading enzymes, which is reported to break down existing collagen while at the same time suppressing the synthesis of new collagen (American Journal of Pathology, 2001). In the clinic, it is common that even at the same age, areas with more sun exposure are thinner and have less elasticity. So I say that the starting point of collagen management is always UV protection.

If you need an article that more broadly summarizes the changes in skin and body with aging, I recommend reading why skin and body change after the forties together.

A woman's collagen change is not explained by calendar age alone. This is because the hormonal inflection point of menopause, in which estrogen decreases, is added. Dermal fibroblasts have receptors that take in estrogen, and estrogen is reported to help the synthesis of collagen and hyaluronic acid through these receptors. When the hormone leaves, the signal of “make collagen” also weakens together.

As a result, several studies report a pattern in which skin collagen decreases markedly during the relatively short period right after menopause, and thereafter decreases gently every year (Brincat et al., 1987). This is why, even at the same age of 50, the skin thickness and elasticity differ between someone who reached menopause early and someone who reached it late. It is easy to understand if you think that collagen follows hormonal age rather than calendar age.

If you are curious about the mechanism of changes throughout the body during menopause, the article on the symptoms, causes, and mechanisms of menopausal bodily changes covers it in more detail.

Collagen is not a protein of the skin alone. Because the same collagen is also used in the scaffold of bone, joints, and ligaments, the decrease in collagen around menopause is known to affect not only skin elasticity but also bone density and joint health. This is why, in the clinic, I also recommend a bone health check-up to those who come for a skin elasticity consultation.

However, there is one point to make clear here. The fact that collagen decreases cannot be asserted to be “reversed” by any single procedure or product. Recovery can differ greatly depending on the individual's hormonal state, lifestyle habits, and skin condition, and medically, the expression “slowing the decrease and helping the synthesis environment” is more accurate.

If you are worried about the change in bone health that comes with menopause, please refer to bone health for women over 50, and if you are curious about your own state, you may also use asking about collagen/elasticity concerns through chat consultation.

Rather than “reviving” collagen, it is more accurate to think of it as creating an environment in which fibroblasts can actively weave collagen again. The factors that govern that environment are generally as follows.

• UV protection: the first step of reducing the biggest external factor that calls forth collagen breakdown.
• Protein/vitamin intake: collagen synthesis is reported to require sufficient protein and coenzymes such as vitamin C.
• Quitting smoking and sleep: smoking and lack of sleep lower the dermis's recovery signals.
• Checking the hormonal environment: around menopause, consider the effect of the estrogen decrease on the skin together.

On top of such a lifestyle base, a medical approach that directly stimulates the dermis to induce synthesis can be added. Representatively, there are methods that give fine stimulation to the skin to draw out a recovery response, or the skin booster class that delivers components that help collagen production to the dermis, and methods such as collagen toning. However, which method is appropriate differs depending on the skin condition and goal, and the degree of effect can have individual differences.

If the lifestyle/procedure approaches above are methods that “help from the outside,” for women around menopause a perspective that “restores the signal from the inside” is additionally needed. This is because the decrease in estrogen itself is the fundamental factor weakening the collagen synthesis signal. In clinical experience, there are many cases where satisfaction is higher when overall menopausal symptoms are examined together rather than managing skin elasticity in isolation.

Hormone therapy is not a treatment recommended uniformly to everyone, but an area where one must carefully weigh gains and losses by considering the individual's medical history and risk factors. So consultation through a visit comes before self-judgment. If you are interested in the hormonal environment, the menopausal hormone guidance or the safe use of local estrogen article can help.

If you feel lost about where to start checking menopausal skin and hormones, please first organize your questions through getting a menopausal skin/hormone consultation via chat without burden.

At the center of declining skin elasticity is the decrease in collagen, and a woman's collagen decreases along the two axes of natural aging and menopause. Collagen is not reversed all at once; it is reasonable to approach it in the direction of slowing breakdown with UV protection and lifestyle management, and, if necessary, adding a medical approach that stimulates the dermis and a check of the hormonal environment to help the synthesis environment. Since the effect and the appropriate method have individual differences, I recommend starting from accurately knowing your own skin and hormonal state.
